In the present study an attempt has been made to compare the role of various organic manures in enhancing the N, P and K value of fly ash. In this regard, various organic manures have been added in different ratios and tested for a given time span. The observations have been made with respect to the Nitrogen, Phosphorus and Potassium content of the fly ash sample, which is subjected to modification. It has been found out that nitrogen content of the fly ash sample drastically rise with the use of poultry (Broiler) manure, whereas the potassium content is getting enhanced by sheep and goat manure extensively. Similarly, the phosphorus content of the fly ash can be enhanced by the use of cow, poultry and sheep dung in combination with the ratio 1:6:3. The results have been incorporated and compared adequately to prepare a modified sample of fly ash with high Nitrogen, Phosphorus and Potassium content
